Let's Talk About Sleep, Baby...

IMG_3032

Sleep is magical stuff.  Missing a night of sleep means you’re missing out on your most productive time for Human Growth Hormone (HGH), which is especially handy stuff when it comes to recovering from a big physical effort.  It’s so handy, in fact, that there’s a booming industry based on the results of HGH supplementation:

Reported effects include decreased body fat, increased muscle mass, increased bone density, increased energy levels, improved skin tone and texture, increased sexual function and improved immune system function. (Wikipedia)

Why, that sounds fantastic.  Luckily, it’s available for free, every single night when you conk out.  It’s better for you, too: making HGH in your very own pituitary gland is waaay healthier than buying the bottled stuff; synthetic growth hormone has a bit of a reputation, it would seem.  There’s a correlation between synthetic growth hormone supplementation in athletes and joint swelling and pain, carpal tunnel syndrome, and diabetes.  Oh, and it’s a banned substance in competitive sports.  Why risk all that when you can go to bed earlier and reap all the benefits with none of the risk?

Unfortunately, a lot of people are sleep deprived and so find themselves struggling through tasks which should be simple, overreacting to situations which should be manageable, and sore as hell from a workout which should not have felt that difficult.  Don’t be that guy.  Aim for 9 hours a night in a completely dark room… you’ll know you’re doing it right because (to quote Robb Wolf) you’ll look, feel, and perform better.

Stressed

Dear readers of the CFTO blog,

Hi. It’s me, Stress.  How are you?  Me, I’m not doing so good.  I’m a little irritated, one might even say stressed by all the bad press I’ve been getting around here lately.  Frankly, it’s unfair.  Where has this anti-stress bias come from?  What would you do without me, huh?  Nothing, that’s what.  Check it out; ABC News thinks I’m not such a bad guy.  Not convinced?  Even Newsweek is on my side.  So give a guy a break, would ya?  Are you trying to give me a complex?  What did I ever do to you?  Actually, don’t answer that.

All’s I’m trying to say is:  Sure, I’ve got my flaws… I might screw with your metabolism, memory, and immune system if we spend every single minute together, but everybody has a friend they can only hang out with for a little while before they start getting annoying and hogging the remote.  Let’s just see each other occasionally, k?

Yours truly,

Stress

The Batcave

Cortisol-3D-balls

It sounds like a Spanish lite beer, and it can give you a saggy midsection… but what is Cortisol, really?  It’s commonly referred to as “the stress hormone”, but that’s only part of the picture.  Cortisol is like Adrenaline’s less-popular, slower-moving sidekick.  They both hang out in the adrenal glands, but for the purposes of the superhero analogy let’s call it the Bat Cave.  Somewhere, something startling/dangerous is happening in Gotham! Quick, Adrenaline, race out of the Bat Cave and make things happen!  Heart rate, up!  Blood pressure, up!  Muscles, contract!  Cortisol will mosey along later, once Adrenaline is exhausted from saving the day.  Cortisol’s superpowers are a little more laid back… it hangs around longer, dumping stored glucose into the bloodstream, improving immune system activity and reducing inflammation.

They sound like a fantastic dynamic duo, and in a lot of cases they are.  In the event of an acute stressor, like a physical attack, it’s important to act quickly.  Adrenaline can give you super strength and reduce the sensation of physical pain.  Cortisol aids Adrenaline using its glucose-releasing action to provide sustained energy, and helps clean up from the aftermath of the Adrenaline dump using its anti-inflammatory powers.  If the stressor persists (i.e. final exams), however, a sustained Cortisol response turns its otherwise immune-raising action into an immune-supressing action, meaning that you’re more likely to succumb to a viral or bacterial infection while under longer-term stress.

Adrenaline and Cortisol are a great line of defense to have ready for rare, unexpected stress… and it’s under these circumstances that this dynamic duo really shines.  If you ask them to save the day all day, every day, however, they get tired and sad and stop being so ready to come to the rescue… if you’re stressed out all the time, your resident superheroes wind up too beat to leave the Bat Cave and you can end up with a nasty case of adrenal fatigue.

Next we’ll look at the link between elevated Cortisol and abdominal fat… in the meantime, have a cup of tea, maybe meditate a little, get some sleep and r-e-l-a-x.
